1990 25 hp yamaha 2-stroke manual start, oil injector.<br /><br />OK - I feel like an idiot. I was lifting my 25 hp outboard up onto the dock to change out the prop without leaning out over the back of the boat. I was holding it by the front handle and the handle built into the top of the engine cover (bad idea). The engine cover latch popped open at an inopportune time and the motor dropped into the drink in 10 ft of water and I was left stading there with the cover in my hand and a dumb look on my face. Dove down and tied a rope to it and hauled it back up. Total time in the water was about 10 minutes.<br /><br />Here's what I did:<br /><br />drained the carbs, took out the plugs and turned the engine over for a couple minutes pushing the water from the cylinders and injecting oil into the cylinders. blew off/ out any eleictrical component areas with compressed air. Inspected the oil resevoir for water (none). I then installed fresh plugs, filled the carbs and it started on the second pull. Let it idle a while to warm up then took it for a spin. Everything seemed to work fine - acceleration, WOT, etc. Used it for about 6 hrs the next day without any problems at all. Is there anyting else I should do to make certain I don't have any repercusions from the dunking?<br /><br />Thanks for any appropriate advice!<br />Dan

Had it in fresh water this weekend - usually run it in salt but it got a good fresh-water rinsing this time.

Re: Drowned Engine Recovery

The mechanicals are fine if you got it running that quickly. You may find that some of the electricals (ignition, etc.) may give you trouble in the future due to water seepage. You may be lucky. :cool:

Re: Drowned Engine Recovery

I'm thinking you are lucky it was fresh water. But like already mentioned, the electricals may have problems later if water creeped in the connectors and stayed too long. I had one that got dunked in salt water and electrical corrosion problems showed up a year later. I'd pull all connectors loose and put dielectric grease in them as a preventive measure. If you ran it a long time it probably dried out.
